Recent rapid advances in flexible electronics, batteries, sensors and catalytic systems demand high performance electrical and electrochemical materials that are stable in an aqueous or humid environment. Copper nanowire (Cu NW) has been considered as an attractive “building block” for nano-device fabrication owing to their outstanding physical, electrical and chemical properties. The poor oxidation resistance of Cu NWs compromises their intended performance in real world applications despite their excellent properties and low cost. It remains a challenge for Cu NWs to be oxidation resistant while maintaining good electrical/electrochemical properties. In this work, several short chain ligands and long chain polymers were chosen to decorate Cu NW surfaces to minimize oxidation. With proper molecular design of the chain length and binding strength, the oxidation resistance of Cu NWs can be greatly enhanced without compromising their electrical and electrochemical properties. Implication of the present research toward preparation of high performance Cu NW-based devices for various microelectronic applications will be discussed.
